DUMPING CAR OR BUGGY.

SPECIFICATION forming part of Letters Patent No. 557,985, dated April 7,1896. Application filed November 13, 1895. Serial No. 568,786. (Nomodel.)

To 00% whom it may concern:

Be it known that I, J OI-INJ Foss, a citizen of the United States, and aresident of Cleveland, county of Cuyahoga,-andState of Ohio, haveinvented certain new and useful Improvements in Dumping Cars or Buggies,of which the following is a specification, the principle of theinvention being herein explained and the best mode in which I havecontemplated applying that principle, so as to distinguish it from otherinventions.

The annexed drawings and the following description set forth in detailone mechanical form embodying the invention, such detail constructionbeing but one of various mechanical forms in which the principle of theinvention may be used.

In said annexed drawings, Figure I represents a side view of my improveddumping car or buggy; Fig. II, a longitudinal section of the same; Fig.III, an end view, and Fig. IV a transverse section on the line IV IV inFig. I.

The principal use for which my invention is intended is as applied tobuggies such as used in rolling-mills and other places where heavy loadsof wire-rod bundles, wire bundles, or other more or less manufacturediron or steel articles are conveyed from one place to another; but itisevident that a dumping device such as herein disclosed may be used forcars of other character and for other purposes by a simple change of thebody of the car.

The car-platform A in the present instance is slightly curvedtransversely, so as to readily shed the bundles of rods when tilted. The

platform has two bracket-frames A near its ends, which frames are formedwith bearings a, pivoted upon trunnions b, projecting from the ends of atruck-frame B. Said frame is provided with axle-bearings I), located ina plane above the plane of the trunnions, and the axles O of thetruck-wheels O are journaled in said bearings. The wheels areillustrated as flanged, so as to travel on rails D, but may be plain.The bracket-frames are preferably so shaped that their diverging sidebraces a will not strike the rails when the platform is tilted, buttheedge of the platform will strike the ties or ground, as illustratedby dotted lines in Fig. III. The truckframe has at its middle atransverse-arched guide B, concentric with the end trunnions,

. Two bolts e and e slide in normally ve'rtr.

cal boxes 6 and e in a cross-frame formed at the middle of the platformby two crosspieces E E,and said bolts slide by their gravity to engagethe shoulders of the ribs, so as to thus hold the platform in itshorizontal position. A roller e is journaled between the cross-pieces totravel upon the arched surface of the guide, and thus reduce thefrictional resistance to the turning of the platform. bracket-bearingsupon the trunnions. Two bolts F and F slide in vertical guide boxes Fand F extending downward from the center of the arched guide, and saidbolts normally register with the gravitating bolts of the tiltingplatform. Each of the lower bolts has a lug f, which projects laterallythrough avertical slot f in the guide-box, so that the bolts may beraised by applying force to their lugs. The bolts drop back into theirnormal lowered positions by their own gravity. I V I I11 practice theplatform may be tilted by applying a crowbar or any similar lever to thelug upon the lower push-bolt, which is accessible from the side wherethe operator stands and the crowbar is applied. The push-bolt may thusbe raised and will raise the upper catch-bolt out of engagement with itsshoulder, so that the platform may be tilted and will drop to the sideaway from the operator. As the car or buggy is principally intended foruse in rolling-mills and similar places for the transportation of heavyloads of metal, which is very frequently at a red heat, it is of greatadvantage to have the dumping mechanism so constructed that the platformcan only tilt to the side opposite the one on which the person actuatingthe mechanism stands. All chance of accident from theplatform and loadtilting over upon the operator instead of away from him is thus avoided.The bolts return to their normal positions by gravity, so that they maybe made very plain and strong and there will be no springs or otherparts to break or get out of order, and thereby prevent the lockingmechanism from operating properly. As soon as the platform is returnedto its horizontal position the catch-bolt, which has been raised and hasbeen bearing against the segmental rib, drops down over the shoulder bygravity, and thus acts as a catch to hold the platform in its normalposition.

By having the pivotal points for the platform in a plane below the planeof the truckwheel axles the car may be made sufficiently low to beconveniently loaded, and at the same time the equilibrium of theplatform will be sufficiently unstable to admit of its being easilytilted when released, notwithstanding its heavy load. The long radiusattained by this arrangement for the are which the platform describeswhen tilted admits of this desirable unstable equilibrium and alsoadmits of the platform assuming a nearly-vertical position when tilted,thereby insuring perfect discharge of the load without undue height ofthe car.

Other modes of applying the principle of my invention may be employedfor the mode herein explained. Changes may therefore be made as regardsthe mechanism thus disclosed, provided the principles of constructionset forth respectively in the following claims are employed.

1 therefore particularly point out and distinctly claim as myinvention-- 1. In a dumping-car, the combination of a wheeledtruck-frame, a platform supported upon said frame to tilt to twoopposite sides, two shoulders upon the truck-frame facing to oppositesides, and two catches upon the platform, each of which engages one ofsaid shoulders to admit of the platform being tilted when one catch iswithdrawn, to that side away from which the shoulder faces, substantially as set forth.

2. In a dumping-car, the combination of a wheeled truck-frame, aplatform pivotally supported upon said frame to tilt to two oppositesides, an arched guide upon the truckframe having raised segmentalportions extending to opposite sides from near the middle of the guideand formed with shoulders at the inner ends of said raised portionsfacing to opposite sides, and two catches upon the platform each ofwhich engages one shoulder and rides upon one raised portion of theguide when the platform is tilted, substantially as set forth.

3. In a dumping-car, the combination of a wheeled truck-frame, aplatform supported upon said frame to tilt to two opposite sides, twoshoulders upon the truck-frame facing to opposite sides, two catchesupon the platform respectively engaging the shoulders, and twopush-bolts arranged in the truck-frame at the bottom of the shoulders tobear against the catches and push them up above the shoulders whenraised, substantially as set forth.

4. In a dumping-car, the combination of a Wheeled truck, a platformsupported to tilt to opposite sides, an arched guide upon thetruck-frame formed with raised segmental portions extending from nearthe middle of the guide to opposite sides and formed with shoulders atthe inner ends of said raised portions, two catch-bolts sliding invertical boxes upon the platform and respectively engaging the shouldersand sliding upon the raised portion, two vertical boxes upon the guideseach of which boxes has its upper end opening at the bottom of ashoulder and a vertical slot in the side facing in the same direction assuch shoulder, and push-bolts sliding in said boxes and provided withlugs which project through the slots in the same, substantially as setforth.

In testimony that I claim the foregoing to be my invention I havehereunto set my hand this 11th day of November, A. D. 1895.
